Cool. Thank you for the comments. I haven't been able to really track the psi from a lot of these builds. I didn't really think that little 1900 was going to get too much past 750 horse', but there's a non-sponsor I've been watching from time-to-time saying they've got a 19-psi package. That is pretty much an entirely new long block package but I know I'd never need to get near that anyways.
I'm a little worried about such a small upper; won't slip become an issue? I haven't really researched a 10-rib swap or anything, or even know if one is available. I was just thinking to keep slip a minimum, that I'd go a 2.55-upper and the 9.5-inch lower. I think Metco makes a kit, too; I just haven't checked. D3 has some great V' parts, but, they're not a sponsor, so you won't see me saying that company much. It looks like I have more research
